"The plane was on its way to South Bend, Ind...The plane's tail number was N873G, a CL-601 Challenger registered to Jet Alliance of Millville, N.J."
The runway at Montrose is 10,000' long (field elevation 5759').
[This] website says the takeoff distance for the model 601-3R is 11,094' on a +20deg day at 5000'. For the model it's 9430' and for the "Global Express" model it's 8490'.
Sure, it wasn't a +20deg day, but isn't this cutting it a little close? (What do I know, I only fly Cessnas...)
